The section of the tube from which the beam emerges includes the heater, cathode, grid and the first accelerating anode; these collectively form the electron gun. A simplified diagram of the connections is given in Figure 11.13. The electric field of the relatively positive anode partly penetrates...
2Cathode Ray Tubes in Evolution Just a century ago J. Plücker2in 1859, W. Hittorf3in 1869, and W. Crookes4in 1879, contrived thecathode ray tubeconsisting of a vacuum vessel in which high-voltage electricity was discharged between a negative pole, the cathode, and the positive anode. All...

Puluj lamp ca 1885 or earlier First medical X-ray in the US Drs Edwin and Gilman Frost using a Puluj lamp for their first X-rays on 3 February 1896, notice the bright light generated by the tube. Here a link to the original PDF article from the Dartmouth Medical school. And here ...
an electron is attracted and accelerated by the positive electrode (aplate, or anode) and is repelled and slowed by the negative electrode (cathode). An electric field can be used to change the path of the electron stream, alter the number of flowing electrons (change the electric current)...
The primary output device in a graphics system is a video monitor. The operation of most video monitors is based on the standard cathode ray tube (CRT) design.
Cathode ray tube with liquid coolant and reduced X-ray emission A digital video display system (DVDS) is disclosed for display of image, alphanumeric and other data on a cathode-ray tube (CRT) with sequential raster scan and two, four or eight gray shades. The DVDS includes a central proc...
An X-ray tube having two individually energizable cathode filaments. If a primary filament is shorted to a cathode cup, a switch mounted inside the tube housing is thrown to couple a second filament to a filament energization signal. This avoids the necessity in replacing the X-ray tube if ...
